We look at the division of 79388427 by 245 
The aim is to understand the frequency of 245 in 79388427.

On to step 1:
7 divided by 245 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 245

Step 2:
If we divide 79 by 245, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 245

Step 3:
When dividing 793 by 245, we get 3 with a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 58 after subtracting 735 from 793.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 245

On to step 4:
245 goes into 588 2 times with a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 490 from 588, we get 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 245

Let's proceed to step 5:
When dividing 988 by 245, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 324.0
If we take 980 away from 988, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 245

Moving on to step 6:
The number 245 fits into 84 0 times, leaving a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 3240.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 245

Moving on to step 7:
842 divided by 245 is 3 with a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 32403.0
Subtract 735 from 842 to get 107.
Take the next digit (7) from the dividend and append it to 107, then repeat: 1077 / 245

Moving on to step 8:
1077 divided by 245 is 4 with a remainder of 97.
Put 4 as the next digit of the answer. 
Result so far: 324034.0
Subtracting 980 from 1077 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
245 goes into 970 3 times with a remainder of 235.
The number 3 becomes the next digit in our result. 
Result so far: 324034.3
The remainder is 235 after subtracting 735 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 10:
2350 divided by 245 is 9 with a remainder of 145.
The next digit of our result is 9. 
Result so far: 324034.39
If we subtract 2205 from 2350, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 11:
245 can be fit into 1450 5 times, resulting in a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 324034.395
Deduct 1225 from 1450 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 12:
245 can be fit into 2250 9 times, resulting in a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 324034.3959
The remainder is 45 after subtracting 2205 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
245 can be fit into 450 1 times, resulting in a remainder of 205.
Write down 1 as next digit of the result. 
Result so far: 324034.39591
If we subtract 245 from 450, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 14:
If we divide 2050 by 245, we get 8 and a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 324034.395918
If we take 1960 away from 2050, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 15:
900 divided by 245 is 3 with a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 324034.3959183
If we take 735 away from 900, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 16:
If we divide 1650 by 245, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 324034.39591836
The remainder is 180 after subtracting 1470 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 324034.39591836 with a remainder of 1.8e-07.
